| Abstract | ||
| Soil survey was conducted during the years 2005 and 2006 for seven Iraqi Governorate representing different climatic and soil stricter for the presence of Bacillus thuringiensis . The results indicated that the best isolation method was the inhibitor with thermal treatment 51.2% of total presence bacterial. The total average of bacterial presence is representing Iraqi soil was 34.5%. The highest presence of bacteria was 50% for Diala and Baghdad. Mortality eate of the bioassay isolation test showed higher 56.7% for Anbar , Baghdad for Tribolium confusum concentration 1.2 x 106 spor / ml. The result of bioassay of Bacillus thuringiensis isolates against Culex pipiems showed mortality 96.9% in Sulimaiyah and Anbar with 1.2 x 105 spor / ml concentration . The bioassay isolates testing spodoptera littoralis showed mortality rate of 96.6% in Diala and Anbar with 1.2 x 106 spore / ml. | ||
